ro ALL WHoM IT MAY concessi:

Be it known that I, GEORGE SEWELL, of Poughkeepsie, in the county of Dutchess, and State of New York, have invented certain new and useful Improvements in Horse-Shoes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which-'- Figure l is an edgejiew of a horse-shoe construct-edaccording to my invention.

Figure 2 is a vertical transverse section of the same taken in the line :vx of figs. 1, 3, and 4.

Figure 3 is a plan view of one portion of the same. Y

Figure 4 is an inverted plan view of another portion` of the same.

Similar letters of reference indicate corresporuling` parts in all the figures.

This invention consists in the construction of Aa horse-shoe with a supplemental detachable portion, whereby that part of the shoe liable to being worn away by use may be readily replaced when'desired,.without the necessity of removing the entirev shoe from the horses hoof. The invention further consists in a novel means of attaching such supplemental-portion to the other part of the shoe, whereby the said attachment is rendered very secure as well as capable of being made with great facility and convenience.

To enable others to understand the nature and construction of my invention, I will proceedtodescrihe it with reference to the drawings. 4 l

A represents the upper portion of the slice, which is designed to be attached to the hoof of the horse in the same manner as an ordinary horse-shoe, by: means of nails passing through the nail holes a. Formed upon the flat lower surface of this upper portion A of the shoe, one at each side, and one at the toe or forward end thereof, is a broad downwardly projecting extension, b, the lower surface of which is dat, and formed in which, in a position lengthwise ofthe shoe, is a tapering dove-tail groove or socket, c, `the rearmost end of which is wider than its forward end. Thelcwer or supplemental portion of the shoe is shown at B. and in its inner and outer circumference correspondsin shape with the upper part A of the shoe. This supplemental portion B is furnished with a toe-calk, el, and with heel-calks, e, of any ordinary or suitable form `and construction, while its upper surface is hat to correspond with thelower surface of the part A, but furnished at each of its heel portions with a low projectiomf, the upper surface of which is broad and flat. Formed upon the aforesaid upper surface of the supplemental part B, one at each side, and4 one at. the forward end or toe thereof, is a tapering dove-tail, g, the said dove-tails'being of such size and shape, and so situated upon the aforesaid part B, that the said part being placed under the part Afand. pushed forward, the dove-tails g will enter and be fitted in to the dove-tail sockets e, and thus attach the portion B to the part A, with the rear extremities of the part A resting upon the ilat upper sides ofthe projectionsf, in order that they may be supported thereby when the slice is in use. Formed upon the upper ysurface of the part B, in front of the extensions situated at the sides thereof, as hereinbcforc described, and at alittle distance from the said extensions, is an upwardly projecting spur, h. The lower part B being attached to the upper part A of the shoe, as just set forth, akey, z', is passed in transversely behind each of the spurs t, or in other Words between the said spurs and the downwardly projecting extension b, situated a little distancein the rear thereof, and thus firmly lock the supplementary part B in place upon the upper part A; any forward movement ofthe part B being prevented. by the dover-tail form of lthe sockets c, and the dove-tails g fitted into them, and any backward movement thereof being eifectually prevented by the transverse keys t', at the same time that by removing the said keys the supplementary portion B may be readily and easily removed, when required, from the upper part .A attached to the hoof of the horse, as, for instance, when it is desired to sharpen the calks d and c. In the making or manufacture-of the two portions A and B of the shoe, it is'vmuch preferred to cast them of steel,`but any other suitable metal, lsuch, for instance, as malleableized cast iron may, if desired, be used in their construction.

What I claim as new, and desire to secure by Letters Patent, isv l 1. The construction of a horse-shoe with a supplementary detachable portion B, substantially as hereinlset forth for the purpose specified.

2. The attachment of the supplementary portion B to the part A of the shoe, by means-of the tapering dove-tails g, tapering dove-tai] sockets c, spurs ll, and keys arranged in relation with each other substantially as herein set foi-th.
